FIELD OF THE INVENTION

This invention relates to benzocycloalkylenylamine derivatives,associated pharmaceutically acceptable salts, or hydrates thereof, andassociated pharmaceutical compositions and methods for use as M2/M3selective muscarinic receptor antagonists.

BACKGROUND OF THE INVENTION

Acetylcholine (Ach) is the principal transmitter of the parasympatheticnervous system. The physiological actions of Ach are mediated byactivation of either nicotinic or muscarinic receptors. Both of thesereceptor classes are heterogeneous: e.g., the muscarinic receptor familycomprises five subtypes (M₁, M₂, M₃, M₄, and M₅) each encoded bydistinct genes and possessing unique pharmacology and distribution.

Almost all smooth muscle tissues express both muscarinic M2 and M3receptors, both of which have a functional role. M2 receptors outnumberM3 receptors by a proportion of approximately 4 to 1. Generally, M3receptors mediate the direct contractile effects of acetylcholine in thevast majority of smooth muscle tissues. M2 receptors, on the other hand,cause smooth muscle contraction indirectly by inhibiting sympathetically(β-adrenoreceptor)-mediated relaxation.

Compounds that act as antagonists of muscarinic receptors have been usedto treat several disease states associated with improper smooth musclefunction. Until recently, most of these compounds have beennon-selective for the various muscarinic receptor subtypes, leading tounpleasant anti-cholinergic side-effects such as dry mouth,constipation, blurred vision, or tachycardia. The most common of theseside-effects is dry-mouth resulting from muscarinic receptor blockade inthe salivary gland. Recently developed M2 or M3 specific antagonistshave been shown to have reduced side effects. Evidence suggests thatconcurrent blockade of M2 and M3 receptors could be therapeuticallyeffective in the treatment of disease states associated with smoothmuscle disorders.

Few M2/M3 selective antagonists have been developed. The presentinvention fills this need by providing these types of antagonists usefulin the treatment of disease states associated with improper smoothmuscle function.

Acceptable inorganic bases include aluminum hydroxide, calciumhydroxide, potassium hydroxide, sodium carbonate and sodium hydroxide.

The preferred pharmaceutically acceptable salts are the salts formedfrom hydrochloric acid, trifluoroacetic acid, dibenzoyl-L-tartaric acid,and phosphoric acid.

It should be understood that all references to pharmaceuticallyacceptable salts include solvent addition forms (solvates) or crystalforms (polymorphs) as defined herein, of the same acid addition salt.

“Crystal forms” (or polymorphs) means crystal structures in which acompound can crystallize in different crystal packing arrangements, allof which have the same elemental composition. Different crystal formsusually have different X-ray diffraction patterns, infrared spectra,melting points, density hardness, crystal shape, optical and electricalproperties, stability and solubility. Recrystallization solvent, rate ofcrystallization, storage temperature, and other factors may cause onecrystal form to dominate.

“Solvates” means solvent addition forms that contain eitherstoichiometric or non stoichiometric amounts of solvent. Some compoundshave a tendency to trap a fixed molar ratio of solvent molecules in thecrystalline solid state, thus forming a solvate. If the solvent is waterthe solvate formed is a hydrate, when the solvent is alcohol, thesolvate formed is an alcoholate. Hydrates are formed by the combinationof one or more molecules of water with one of the substances in whichthe water retains its molecular state as H₂O, such combination beingable to form one or more hydrate. “Prodrug” means a pharmacologicallyinactive form of a compound which must be metabolized in vivo, e.g., bybiological fluids or enzymes, by a subject after administration into apharmacologically active form of the compound in order to produce thedesired pharmacological effect. The prodrug can be metabolized beforeabsorption, during absorption, after absorption, or at a specific site.Although metabolism occurs for many compounds primarily in the liver,almost all other tissues and organs, especially the lung, are able tocarry out varying degrees of metabolism. Prodrug forms of compounds maybe utilized, for example, to improve bioavailability, improve subjectacceptability such as by masking or reducing unpleasant characteristicssuch as bitter taste or gastrointestinal irritability, alter solubilitysuch as for intravenous use, provide for prolonged or sustained releaseor delivery, improve ease of formulation, or provide site-specificdelivery of the compound. Prodrugs are described in The OrganicChemistry of Drug Design and Drug Action, by Richard B. Silverman,Academic Press, San Diego, 1992.

“Subject” means mammals and non-mammals. Mammals means any member of theMammalia class including, but not limited to, humans, non-human primatessuch as chimpanzees and other apes and monkey species; farm animals suchas cattle, horses, sheep, goats, and swine; domestic animals such asrabbits, dogs, and cats; laboratory animals including rodents, such asrats, mice, and guinea pigs; and the like. Examples of non-mammalsinclude, but are not limited to, birds, and the like.

“Therapeutically effective amount” means an amount of a compound that,when administered to a subject for treating a disease state, issufficient to effect such treatment for the disease state. The“therapeutically effective amount” will vary depending on the compound,and disease state being treated, the severity or the disease treated,the age and relative health of the subject, the route and form ofadministration, the judgement of the attending medical or veterinarypractitioner, and other factors.

“Pharmacological effect” as used herein encompasses effects produced inthe subject that achieve the intended purpose of a therapy. In onepreferred embodiment, a pharmacological effect means that primaryindications of the subject being treated are prevented, alleviated, orreduced. For example, a pharmacological effect would be one that resultsin the prevention, alleviation or reduction of primary indications in atreated subject. In another preferred embodiment, a pharmacologicaleffect means that disorders or symptoms of the primary indications ofthe subject being treated are prevented, alleviated, or reduced. Forexample, a pharmacological effect would be one that results in theprevention or reduction of primary indications in a treated subject.

“Disease state” means any disease, condition, symptom, or indication.

“Treating” or “treatment” of a disease state includes:

(1) preventing the disease state, i.e. causing the clinical symptoms ofthe disease state not to develop in a subject that may be exposed to orpredisposed to the disease state, but does not yet experience or displaysymptoms of the disease state;

(2) inhibiting the disease state, ie., arresting the development of thedisease state or its clinical symptoms; or

(3) relieving the disease state, i.e., causing temporary or permanentregression of the disease state or its clinical symptoms.

Non-specific binding was defined with 1 μM atropine. Assays wereperformed using scintillation proximity assay technology.Competition-displacement curves were generated using 10 concentrationsof test compounds and were analyzed by iterative curve fitting to a fourparameter logistic equation. pIC₅₀ values (−log of the IC₅₀) wereconverted to pKi values using the Cheng-Prusoff equation.

EXAMPLE 16 Oxotremorine/Pilocarpine-Induced Salivation (OIS/PIS) Modelin Anesthetized Rats

Female Sprague-Dawley rats (Charles-River, 200-300 g) rats wereanesthetized with urethane (1.5 g/kg, sc) and were tracheotomized. Onefemoral vein was cannulated for drug administration. After a one hourstabilization period, rats were pre-treated with methoctramine (only forOIS) to antagonize M₂ receptor mediated bradycardia. Each animal wasdosed, intravenously, with a single dose of the vehicle or the referencecompound. Ten minutes later, pre-weighed cotton pads were placed in theanimals mouth following which they were dosed with vehicle oroxotremorine (0.1 mg/kg, iv)/pilocarpine (1 mg/kg, iv). Fresh cottonpads were placed at 5 minutes post-oxotremorine/pilocarpine and salivacollected for an additional 5 minutes. The cotton pads (5 and 10-minuteperiod) were then re-weighed to determine the amount of saliva secretedduring the 10-minute period.

All oxotremorine/pilocarpine treated groups were compared using one-wayanalysis of variance. Pair-wise comparisons were made using Dunnett'stest. The ranked data (non-parametric technique) or actual levels of thedata (parametric technique) are applied in the analysis depending uponthe results of the Bartlett's test, which tests homogeneity ofvariances. The vehicle/oxotremorine group and vehicle/pilocarpine wascompared to the vehicle/vehicle group using Wilcox on rank-sum test. Anestimate of the ID₅₀ for each compound with respect to the 10 minuteoverall secretion weight for each animal was obtained. The sigmoidalmodel is in the form of

Resp=min+(max−min)/(1+(dose/ID₅₀)**N)

where ID₅₀ is the dose to achieve half the maximal response, N is thecurvature parameter and max is the max response for the dose responsecurve. The minimum response was fixed at 0 in the model.

Compounds of this invention were active in this assay.

EXAMPLE 17 Inhibition of Volume-Induced Contractions in Rats

The muscarinic receptor inhibitory activity of compounds of thisinvention in vivo was determined in rats using a modification of themethod described in Hegde, S. S. et al. (1996) Proceedings of the 26thAnnual Meeting of the International Continence Society (August 27th-30th), Abstract 126.

Female Sprague-Dawley rats were anesthetized with urethane andinstrumented for intravenous administration of drugs and, in some cases,measurement of arterial pressure, heart rate and intra-bladder pressure.The effect of test compounds on volume-induced bladder contractions wasdetermined in separate groups of animals. Volume-induced reflex bladdercontractions were induced by filling the bladder with saline. The testcompounds were administered intravenously in a cumulative manner at10-minute intervals. Atropine (0.3 mg/kg, iv) was administered at theend of the study as a positive control.

Compounds of this invention were active in this assay.

EXAMPLE 18 Anti-muscarinic activity in anesthetized dogs

The muscarinic receptor inhibitory activity of compounds of thisinvention in vivo was determined in dogs using a modification of themethod described in Newgreen, D. T. et al.( 1996) J. Urol., 155 (Suppl.5), 1156.

Female beagles (Marshall Farms, North Rose, N.Y.) were fasted for 18hours prior to the experiment; water was allowed ad libitum. On the dayof the experiment, dogs were anesthetized and maintained onpentobarbital (36 mg/kg, iv initially, then 5-10 mg/kg, iv formaintenance). Intravenous fluids were also administered to the dog forthe remainder of the experiment. The dogs were artificially ventilated,via an endotracheal tube, with an Harvard respirator (Model 613). Bothfemoral veins and one femoral artery was cannulated for drugadministration and blood pressure measurement, respectively. Bloodpressure was measured with a Gould transducer (Model P23XL) and recordedon a Gould recorder (Model 3400). A sublingual incision was made toexpose the left mandibular duct, which was then cannulated for thecollection of saliva into pre-weighed vials. The left salivary gland wasexposed via a submandibular incision. The chorda-lingual nerve wasisolated and had a bipolar electrode placed on it for stimulation. Testresponses to chorda-lingual nerve stimulation were obtained to confirmproper electrode placement.

After completion of surgery, physostigmine (180 μg/kg/hr, iv) (acholinesterase inhibitor) was infused for the remainder of theexperiment. Following a one hour stabilization period, two controlchorda-lingual nerve stimulations were performed at 12 Hz, 10 V, 0.5 msduration (Grass S48). The chorda-lingual nerve was stimulated for 20seconds and 2 minutes, respectively, with a minimum of 10 minuteinterval between each set of stimulations. After two consistent controlresponses were obtained, the vehicle or the reference compound was dosedin a cumulative fashion, 3 minutes prior to each stimulation of thechorda-lingual nerve. Experiments in which consistent salivationresponses could not be obtained were not included in the analysis.Atropine (1.0 mg/kg, iv) was given as a positive control at the end ofthe study.

Mean arterial blood pressure was calculated as Diastolic arterialpressure+(Systolic arterial pressure−Diastolic arterial pressure)/3.Heart rate was derived from the pressure pulse. Saliva was collected inpre-weighed vials and weighed after each collection to determine thevolume of saliva secreted. Inhibition of salivary gland responses wereexpressed as a percent of the effect of atropine (1 mg/kg, iv).

ED50 Estimation

For % max inhibition salivation, parameter estimation was performedusing a nonlinear mixed model. The method was implemented using PROCNLIN initially and PROC MIXED iteratively. This procedure assumed thefollowing sigmoidal dose-response model:${Response} = {{Min} + \frac{{Max} - {Min}}{1 + 10^{- \frac{({x - \mu})}{\sigma}}}}$

where response=% max inhibition bladder contraction at peak, x=log₁₀dose of treatment and the 4 parameters were: log₁₀ ED50 (μ), maximum andminimum response (Max and Min), and curvature (σ). The minimum wasassumed 0%. This method assumed compound symmetry for the covariancestructure. It was an iterative curve-fitting procedure that accountedfor the dependence between multiple measurements from the same animal,and estimated the desired parameters and their confidence limits byadjusting its error calculations to account for within subjectcorrelation.

Baseline Comparisons

To compare each dose to baseline control for every variable, a two-wayANOVA with main effects of subject and treatment was performed, followedby a pair t-test at each dose level. If the overall treatment effect wasnot significant (p-value>0.05) in ANOVA, a Bonferroni adjustment forp-values was used for the p-value of pair t-test at each dose.

Compounds of this invention were active in this assay.
